CURLING- TONGS PROVIDED WITH HEATABLE IRONS Application filed August 17,1927, Serial No.

This invention relates to curling tongs pro- I vided with heatableirons.

Curling tongs with heating devices of all kinds have been generallyknown, but they have-one and all-the inherent disadvantage, that theyare operated by using glowing bodies, which are warmed to glow heatoutside of the iron and then introduced into same. This method entailsvery considerable fire hazards and requires the presence of a separatesource of heat.

It is a purpose of this invention to create curling tongs, ondulatingirons and similar devices, provided with a hollow into which the heatingbody is introduced. The latter Y is then ignited by means of a fuse origniting cap and burns out in the closed chamber without the admissionof oxygen, communicating its glowing heat to the irons of the tongs andwarming same to the degree required. By employing this method any firehazard as f. i. the ignition of liquid or gaseous fuels or the catchingon fire of the hair to be ondulated or similar dangers are quiteexcluded.

In order to attain this aim it is possible to heat either one or bothirons of the tong (profile irons or pressing irons) by means of heat--ing bodies, which are inserted into the hollow parts of the tongs andburn without the introduction of oxygen or heat of any kind brought tobear in these bodies from outside, the hollow parts being completelyclosed.

The heating bodies inserted carry igniting caps by the friction of whichthe former are set afire. When these heating bodies are burnt out thereremains a strong skeleton which can completely be withdrawn from theiron together with the products of the combustion. The heating body iscomposed of oxygen supplying material as saltpetre and fuel, asmagnesium, for example a so-called sparkler, so that after the ignitionit is capable to glow and burn slowly in a closed container without theadmission of oxygen, communicating its heat to its surroundings.

In Fig. 1 the hollow iron 1 of an ordinary curling tongs is shown, thebore 3 of which nearly reaches the turning point 4. The counter iron isexecuted in the usual manner 2 3,505, a d in Au ria membe 6 1 6- andis-when the tongs are shut-warmed together with the other iron, the twoirons,

Whichar turna e ro nd the x 5., bein brought into such an intimatecontact by the ompression o he andl s tha the mbustion of the heatingbody'inserted warms them both at the same time.

Fig. 2 shows a cross section of the iron 1 with the bore 3 extending asfar as point 4:.

Fig. 3 shows a specimen of a heating body 7 with igniting cap 8, whichmay be ignited at any friction surface used for matches. It is supportedby a metal skeleton 9, which after "combustion may be withdrawnaltogether from the. iron, thereby cleaning the latter.

Fig. 4 illustrates the cross section of both irons shown in Fig. 1 withthe same reference numbers.

Fig. 5 shows the cross section of a curling tong of which both irons aremade hollow (refer to Figs. 3 and 6).

Fig. 6 shows an ondulating iron with 3 hollow irons 1 which fit into thecavities of the ondulating iron 2 and whichafter the combustion of the 3glow bodies-heat also the ondulation iron.

I claim:

1. A curling iron of the character described, comprising a. pair ofpivotally connected aws and handle members for manipulating the same,one of said jaws being hollow and open at its outer end, and a removabledry solid combustible cartridge adapted to be inserted in the hollow jawat its open end to project beyond the same, and to be ignited to heatsaid iron.

2. A curling iron of the character described, comprising a pair ofpivotally connected jaws and handle members'for manipulating the same,one of said jaws being hollow and open at its outer end, and a removabledry solid combustible cartridge adapted to be inserted in the hollow jawat its open end to project beyond the same and terminating at its outerend in an ignition cap projecting, when the combustible cartridge isinserted,

beyond the outer end of the said jaw whereby I said cartridge may beignited.

scribed, comprising a pair of pivotally connected j aws and handlemembers for manipulating the same, one of said jaWs being holloW andopen at its outer end, and a removable dry solid combustible cartridgeembodying a skeleton support therefor and adapted to be inserted andignited therein to heat said iron, the residue being removable therefromthrough said skeleton support.

4. A curling iron of the character described, comprising a pair ofpivotally connected jaws and handle members for manipulating the same,one of said jaws being hollow and open at its outer end, and a removabledry solid cartridge composed of fuel and oXygen-providing material incorrect proportions to burn the fuel Without external supply of oxygensaid cartridge being adapted to be inserted in the hollow j aW at itsopen end to project beyond the same and be ignited to heat the saidiron.

In testimony whereof I affix my signature.

LUDWIG SPITZSTEIN.
